Abstract (en)
[origin: EP3435738A1] A microwave treatment apparatus (101) comprises: a heating chamber (11); an oscillation source (1) that generates a microwave; a base plate disposed in the heating chamber (11) for placing thereon a heated object (7); and a waveguide (6) that guides the microwave into the heating chamber. The microwave treatment apparatus (101) further comprises: a periodic structure (5) disposed in the waveguide for causing the microwave to propagate in a surface wave mode; a detection antenna (9) near the periodic structure (5); a detector that detects an electromagnetic wave received by the detection antenna (9); and a controller (10) that controls the oscillation source (1). The controller (10) recognizes a power distribution of the electromagnetic field near the periodic structure (5) based on the detected electromagnetic wave and causes the oscillation source (1) to set the oscillation frequency to either a first oscillation frequency or a second oscillation frequency according to the power distribution of the electromagnetic field. In this aspect, a desirable power distribution of the electromagnetic field near the periodic structure can be maintained by correcting a characteristic change of the periodic structure.
